The site as it stands is fine for a straight up svnpubsub setup, but not for the CMS. Can I suggest you read through http://www.apache.org/dev/cms.html
and all it's related links.
You'll need to create the mdtext files for CMS, not produced html etc. Thats what the CMS does for you.
For example, look at https://svn.apache.org/repos/asf/incubator/ctakes/site/trunk/
